我试过了

go get -u google.golang.org/grpc

但仍然遇到同样的问题。我的grpc版本是v1.26.0

有什么解决办法吗？

Answer 1

您确定您的版本是 v1.26.0 吗？你能分享你的 go.mod 吗？

go get -u google.golang.org/grpc

以上命令是获取最新版本的grpc，即v1.27.1

一旦您将 go.mod 中的版本从

更改为

google.golang.org/grpc v1.27.0

至

google.golang.org/grpc v1.26.0

您需要运行以下命令来锁定版本：

go get google.golang.org/grpc@v1.26.0
